Stata files:

If the Seki-Williams Annual Government Partisanship dataset is not what you need, then you can modify temporal dimension (i.e., quarterly or monthly), change the unit of analysis to government-party, or create different government partisanship variables, then use the following Stata do file:

Seki-Williams Government Partisanship: Stata do file that uses the Manifesto Project Database (e.g., left-right position, dove/hawk position, etc) to produce partisanship data (based on the prime minister's position and the government's position weighted by seats) at a variety of units of analysis (annual, quarterly, monthly or daily). NOTE: This produces a data set with the government/time period as the unit of analysis, meaning that there will be multiple observations for the time periods where a government change occurs. For example, in a government/year data set, there will be multiple observations for the year of an election. Also, this dataset uses the latest update of the manifesto data (Update 2016a), so make sure that you download it from the link below and save it in the working directory.
